Abstract
The NEVOD experimental complex includes several installations for the joint study of various components of extensive air showers (EAS). One of the installations is the calibration telescope system (CTS). This installation is used for calibration of the measuring modules of the Cherenkov water detector, as well as for recording the electron-photon and muon components of the EAS. The reconstruction of the EAS parameters according to the CTS data aims to improve the capabilities of the entire experimental complex for studying showers in the region of primary particle energies from 0.1 to 10 PeV. The main task of reconstruction is to determine the coordinates of the EAS axis position using the maximum likelihood method. The iterative simplex method of Nelder-Mead is used to find the optimal values of the parameters. The accuracy of the reconstructed parameters was estimated on simulated events. The simulation was based on the Nishimura-Kamata-Greisen lateral distribution function for EAS charged particles. The results of reconstruction of the parameters of the EAS registered in the upper plane of the SCT are presented.
